Four beta-carboline alkaloids, brunneins A-C (1-3) and 3-(7-hydroxy-9H-beta-carboline-1-yl)propanoic acid (4), were isolated from fruiting bodies of the agaricoid fungus Cortinarius brunneus. The structures of 1-3 were determined by analysis of NMR and MS data, and the structure of compound 4 was determined by comparison with published data. Brunnein A (1) exhibited very low cholinesterase inhibitory effects and no cytotoxicity.
从伞菌状真菌褐丝膜菌的子实体中分离出四种β-咔啉生物碱,即褐丝膜菌素A-C(1-3)和3-(7-羟基-9H-β-咔啉-1-基)丙酸(4)。通过核磁共振(NMR)和质谱(MS)数据分析确定了1-3的结构,化合物4的结构则通过与已发表数据进行比较得以确定。褐丝膜菌素A(1)表现出极低的胆碱酯酶抑制作用且无细胞毒性。
